I'd reach out to your state's commission for the blind (assuming you live in New York, that number is 1-866-871-3000) and if you're not already registered with them, talk about getting registered and once you are, ask about getting Orientation and Mobility lessons. An instructor will come out, talk to you about your goals and what you want to learn, and they can help you figure out routes to get to places you usually like to go, as well as general travel skills.

Speak with your doctor about vision changes. We are unable to provide medical advice.

Visions is a great organization that operates out of NYC and provides services such as vision rehab, orientation & mobility, and social workers.
